Application led October 19, 1914. Serial No. 867,303.

T0 all 'whom t may concern:

Be it known that we, RICHARD F. Ln BROCQ, a citizen of the UnitedStates, and a resident of the city of New York, county of Kings, andState of New York, and KARL J. J. SCHMUTZLER, a citizen of the UnitedStates, and a resident of New Dorp Manor, Richmond county, New York,have invented a new and useful Improvement in Door- Closers, of whichthe following is a full, clear, and exact description. l

Our invention relates to improvements in door closers and the object ofour invention is to produce a simple, inexpensive and positive apparatusin which a weight is used 1nstead of the customary spring, and in whichthe parts are assembled and arranged in such a manner that the operationof the device is absolutely positive 4so that the door is sure to closewhen it is released in an open position.

Our invention is also intended to provide a very inexpensive structurewhich canV be easily applied to a door and an adjacent wall or support,and which when used very frequently, as for instance on the door of afactory or other place, will not get out of order.

Reference is to be had to the accompanying drawings forming a part ofthis specilication, in which similar reference characters indicatecorresponding parts in all the views.

Figure 1 is a side elevation of our improved door closing apparatus asapplied to a door.V Fig. 2 is a sectional plan on the line 2-2 of Fig.1, and Fig. 3 isa section on the line 3 3 of Fig. 2, showing the slidingcarriage in end elevation.

The door 10 is provided with a plate 11 which connects with a pintle 12on the rod 13, and the latter is pivoted as shown at 14 to the stud 14aon the sliding carriage 15. Obviously the particular connection with therod 13 is not important, as the essential thing is to have a pivotalconnection by means of the rod and link between the door l0 and thesliding carriage 15.

The carriage 15 is preferably formed of plates 16 and 17 which arespaced apart as shown clearly in Fig. 3, and the stud lsL on the plate17 is recessed on the under side to form a bearing or saddle which rideson the guiderod 19. This latter is horizontally arranged behind the dooron the wall or other support adjacent to the door, the guide rod havingits ends inturned and secured by means of plates 20 or otherwise to theadjacent wall or support. Thus when the door is opened or closed, thecarriage 15 will slide horizontally on the rod 19.

Between the plates 15 and 16 of the carriage and preferably near theends thereof, are rollers 2l which are arranged in pairs as shownclearly in the drawing, and these rollers serve to prevent friction, asthey are engaged by the swinging leg 22 which enters vertically betweenthe pairs of end rollers.l This leg 22 extends normally in a verticalposition parallel with the back edge of the door as shown in Fig. 1, andat its upper end it merges into a head 23 which is pivoted near the topas shown at 24. In the head 23 is a curved cam slot 25 which is arrangedin a generally vertical position, and this receives the pin 26 on theweighted arm 27, the latter extending in a generally horizontal positionabove the door, and being pivoted at one end as shown at 28, while itsopposite or free end is provided with a weight 29. Obviously the arm 27may be made sufficiently heavy without the weight, and it is equallyobvious that any suitable anti-friction devices can be used to form thecam connection between the arm and the head 23.

The above described mechanism is extremely cheap and simple, and easilyapplied. When so applied and the door is opened, as shown by dottedlines in Fig. 2, the rod 13 will push the carriage 15 along the guiderod 19, and the carriage will swing the leg 22 to the position shown bydotted lines in Fig. 1, and raise the weighted arm 27, as indicated bydotted lines in same figure. When the door is released, the weighted arm27 will by means of its pin and cam slot connection with the head 23,cause the head and leg 22 to swing toward the door, thus moving thecarriage 15 and closing the door by means of the connection between thecarriage and the door already described.

From the foregoing description it will be seen that there is nothing toget out of order about this structure, and that the parts can be cheaplymade, assembled, and put in place.
